Best Automotive Tap and Die Set for Pro Mechanics

If you operate an auto repair shop or restore old cars sooner or later you will have the need to cut internal or external threads.

Auto manufactures design their products with industry specific fasteners that utilize unique thread series and sizes.  Most tap and dies sets are for general purpose use and may not have the right sizes included. That’s why its important to have the best automotive tap and die set readily available when the job requires it.

If you are an experienced mechanic chances are you have run across a repair or restoration job that involves cutting new threads or cleaning up old ones.  If you don’t have a tap and die set on hand, tracking down the right size tool can be a time-consuming and frustrating process that can hold up your whole project.

First of all you have to identify the diameter of the thread and the thread pitch.  That requires a thread gauge that many mechanics just don’t have in their tool box.  And then once you have determined the correct size, tracking down the right tap or die online, placing the order, and waiting for it to be delivered can take several days.

My Recommendation

What I like most about the Astro Pneumatic Automotive Tap and Die Set 7582 is that it includes the sizes that cover 95% of all METRIC thread fasteners typically found on an automobile. This is a 75 Piece Master set that includes all the necessary accessories to do a professional threading job.

It includes a uniquely designed 72 tooth Ratcheting Wrench that pairs with the Hex Die Holder and the (2) Tap Drive Holders.  Or, for those tight clearance jobs you can use a standard 3/4″ socket and ratchet wrench (NOT Included).  A Thread Gauge is included in the set so there is no guessing what thread size you are dealing with.
Each tap and dies is machined from imported Japanese alloy tool steel that can withstand the stresses that would cause the typical high carbon steel or TiN-coated sets to fail.

The Astro Pneumatic Tool 7582 Automotive Tap & Die Set comes with (9) Plug Taps, Sizes: M5x0.8, M6x1.0, M8x1.0, M8x1.25, M9x1.25, M10x1.25, M10x1.5, M12x1.25, M12x1.75 and (9) Hex Dies, Sizes:  M6x1.0, M8x1.0, M8x1.25, M10x1.25, M10x1.5, M12x1.25, M12x1.5, M12x1.75.

Also included with the set is a screw driver and a rugged plastic storage case.

If you are a serious mechanic the Astro Pneumatic 7582 is the best automotive tap and die set currently available!
